摘 要 汽车覆盖件是指构成汽车车身或驾驶室、覆盖发动机和底盘的金属板 料制成的异形体表面和内部零件。它既是外观装饰性的零件，又是封闭薄 壳状的受力零件，具有材料薄、形状复杂、结构尺寸大和表面要求高等特 点。 本文首先阐述了汽车覆盖件当前在国内外的发展现状及发展汽车覆盖 件模具的重要意义。在第二章中主要是介绍了使用 Dynaform 进行产品的模 拟，详细的介绍了本产品的模拟过程，通过对模拟结果的后处理，不断修 改影响的主要参数以期达到理想的结果。在第三章主要是介绍了产品的模 具设计，通过模拟结果进行一整套的模具设计，再使用 UG 进行了三维造型。 最后总结了全文，对本课题进行了展望。 关键词：汽车覆盖件，模具设计，板料成形模拟  ABSTRACT Automobile panel refers to automobile body or the cab of car, the coverage of engine and the chassis are made of sheet metal of the shaped surface and internal parts. It is not only the appearance of decorative parts, but also a closed shell-shaped parts by the edge with a thin material, shape, complexity, structure size and the high surface requirements. This article first introduces of the development of the current status and development of automobile panel significance at home and abroad. In the second chapter is to introduce use Dynaform to simulate product, presented a detailed simulation of the product, through the post-processing of simulation results and continuously modify the effects of the main parameters to achieve the desired results. By the results of simulation in the third chapter is mainly to introduce the product mold design, and then carried out using three-dimensional software –UG to make model. Finally summed up on the subject of the prospect Keyword：Automobile panel, mold design, sheet metal forming simulation  目 录 摘 要 ................................ ............
